Terrible Mpg?

2013 5.7 SR5 DC factory 20" wheels. I'm averaging 14.6 over hilly, winding western PA highway. I'll get close to 20mpg on a turn pike cruise down hill.

 

4.6L, 20" wheels, no lift, 91octane, light foot Daily Driving, 25 mile round trip, split between highway and city with metro traffic...constantly average 16.5 - 17 mpg

 

Okay wtf. I get like 13. I'm lifted 3 inches and when I fill up I fill up 22gallons. And I'm at 260 miles when i do fill. Stop making me feel horrible

 

I get 17mpg in town. Works for me haha

 

As said before, try doing a hand calc for fuel economy. Just because I'm curious and somewhat OCD I always cross reference a hand calc with the on board CPU. there is a difference!

It may also be worth looking at your suspension components?

 

What would I look for. I just did a toytec lift. I do have a wheel bearing noice which I'm putting off because I hate doing them. I filled up 22 gallons and had 270 on the clock. That's 12.4 mpgs or whatever

 

I've seen a number of very interesting "lift jobs"

blown out shocks reinstalled, loose spacer bolts, worn ball joints, even bent A arms causing excessive toe/ camber.

just trying to offer ideas brotha!

 

I put it in myself. I do need an alignment tho that's for sure. Have you or anyone heard of this driver side lean. When I did the install I put the spacer they provided to me on the driver side and it's still a little lean

 

270 miles is correct w the lift and tires u have. that's what lotsa guys here get including me..

 

Thanks. I feel a little better. Trying to stop throwing Bill's out my window lmfao

 

I just drive this gas guzzler less..that's the efficient way of getting the most mpgs..

 

Nooooooo I guess time to find a taco

 

My 08 RCSB 5.7 4X4 was getting 16mpg mix driving. After a 3" lift and 35" tires, i'm down to 13mpg. I do drive like a douche and the sensitive pedal doesn't help. Would I wish I had gotten something else? Hell no! Actually if someone with a 2019 TRD Pro Taco came up to me and asked to trade straight up i probably would.

 

Wait, nvm, that 3.5L is weaksauce, can't do it.

 

2013 SR5 crewmax 4:30 gears, leveling kit,305/55/20's, dual BAMufflers with x-pipe and 2 1/2" pipes both out the passenger side,k&n pan filter with tonneu cover. 14.5 to 15 mpg. I don't poke around!

 

TRD Pro Crew Max with 5.7. I consistently get 12.5 to 13 city, and 16 Hwy. Beast mode = 10.5 city. No BS on these numbers. Let’s face it, people don’t buy Tundras for gas mileage.

 

I drive my truck, its part welding truck, part nice business/construction meeting truck. It tows trailers almost everyday and I get 14.2 pretty regularly. If im really nice to it and im flying solo (no trailer) I get 15.9. To me, that's decent for almost 400 HP and burning gasoline.

 

I have a 2007 Tundra SR-5, 5.7. I'm averaging 17.1 mpg with stock SUV rated tires. I drove a 2000 Isuzu Trooper for 18 years with a 3.5 V6 that averaged about 17.0 mpg with 215 hp. I'm very satisfied with 17.1 mpg on a 380hp engine with a super smooth ride and quiet cab. Next month I'm installing cold air low restriction intake. Will report results.

 

Unless I’m on a road trip I use regular with Lucas. Seems like the everyday drive and hi octane don’t mix, but a constant draw on the fuel and it’s ok

 

I was getting 14-19 from my 3.7 V6 F150 so 13-17 from my Tundra is a blessing all that 5.7 raw power for a few $$ more, I’m good with that.

 

I hit 25 mpg or so whenever I head east out of Silverthorne on the I70. Dropping 5,000 feet of elevation in 50 miles sure helps the numbers! I get about 15 mpg the other way...

 

3" lift and 35" tires on, i avg 13.5 between city and hwy driving. 50/50, not bad, about the same as my V12 Benz and LX470 on 33's
